2 sets of dishes

Question

Dear RAbbi Abadi, I am far from being a great ssdcholar, but it did seem to me when looking at Yoreh Deiah during yomtov, that the only prohilbition on utensils was not to cook meat and then mile et in a keli that is not beben yomo, otu, you might do this with a ben yomo. surprisingly to me at least I i think 103 and 123) there was nothing mentioned about avoiding cold meat and milk and the same dishes or having two seperate sets of utensils. am i reading this correctly?
